Decoking System – Rotary Joint-VOIDSRJ4191810

The Voltex Industries VOIDSRJ4191810 Rotary Joint is robustly designed to support the suspended loads experienced in decoking units. It serves two key functions. First, it transfers water from the decoking hose to the drill stem and has a sealing system to allow the high-pressure water from the jet pump to pass into the rotating drill stem without leakage. Second, it provides rotational movement of the complete drill stem and cutting tool assembly by way of a driver mounted on it.

  • The Decoking System VOIDSRJ4191810 Rotary Joint drive options – Air piston, electric-over-air, hydraulic or electric motor (with VFD)
  • Standard dual seal increases reliability with a three-year design life; secondary seal allows six additional months to plan for maintenance
  • Integrally cast, single-piece gooseneck and support cage eliminates welds and reduces corrosion.
